High-strength steels and laser welding are increasingly popular in car body manufacturing. But combining those two things leads to a significant risk of hot crack formation. Now there’s a solution.
BAM study by Michael Rethmeier says: Laser welding in car body construction is more ecological that resistance-spot welding.
3D scanner optics work autonomously. Welding optics control the temperature of the plastic melting process, and fixed optics monitor the state of the process. In Industry 4.0, optics have their own minds, too.
The automotive industry has long enjoyed the benefits of lasers and rail vehicle manufacturers could follow suit. This was the thinking behind setting up Photon AG and its latest signature project is proof that this idea was spot on.
Magnesium alloys could be a dream solution for lightweight construction. Unfortunately, welding them is still a nightmare – but maybe not for much longer.
Eight ways to cut and join the lightweight materials aluminum, plastics and CFRP using lasers.
A newly developed pulsed green laser welds copper with high reproducibility and little spatter – regardless of the nature of the surface.
Automotive giant GKN Driveline started welding drive components with lasers 14 years ago. Now the tried-and-tested system is moving to the next round — featuring disk lasers — on three continents.
Joining materials that have long been considered unweldable is one of the biggest challenges in lightweight engineering. The laser offers some promising solutions.
Copper on aluminum: With a cycle time of 72 seconds and high tensile strength, Viessmann has got itself precious breathing space.
An operating table must be adaptable to every need and at the same time totally reliable. That is why the company that was to become TRUMPF Medical Systems adopted laser welding long before it joined the TRUMPF Group.
Whether 3D printers will some day be found in every home shop remains to be seen. But one thing is certain: generative processes are well on their way to maintaining health and saving lives.
Induction is proving to be an ideal partner for laser welding: for pre-heating, cleaning and hardening
Thanks to new PFO 3D programmable focusing optics, the focus spot now enjoys more freedom of movement than ever before. What’s more, “CalibrationLine” is on hand to ensure that the laser hits the spot each and every time.
“Power of Choice” is the slogan that best describes the numerous new laser beam sources for material processing TRUMPF will be presenting at the LASER World of Photonics 2013.
Dr. Dietrich Freiherr von Dobeneck explains his driving passion for electron beam welding and his determination to compete with lasers.
To make electric drives affordable, we need to work out details such as how to produce millions of laminated cores cost-efficiently.
A look inside the multi-faceted future of hybrid laser welding.
Uwe Stadtmüller, in his middle-market business, has adopted laser welding in three-dimensional space to manufacture fan guards.
The wobble method is taking the automotive industry by storm. It offers all the advantages of remote welding, plus it bridges gaps between the surfaces being joined. That cuts down on costs and above all weight.
Who would have thought that combining the costly vacuum technology of electron beam welding with the beam of a solid state laser could be so effective?
What is going on Down Under? Annaliese Kloe from Headland Machinery names the trends driving Australia's laser industry.
It would be so convenient during remote welding for the laser to position the necessary cut-out using the same scanner optic. It is time for a new process.
For all the usefulness of coatings, they can be an impediment when welding. Which is where the cleaning power of short-pulse lasers comes in.
Up to date electronic manufacturing without laser? Unthinkable! Many products would be quite simply impossible.
“Wherever production is high, there’s a similar need for lasers and laser systems. This increasingly applies to China, now and in the future,” says Günther Weinmann, General Manager Laser Technology at TRUMPF China.
It doesn’t get any tougher: Dirt, vibrations, heat — laser welding machines do their work reliably at the entry to the cold rolling mill. Nonstop. Coil by coil.
The food industry wouldn’t be the same without the laser.
What advice does automotive laser expert Hongping Gu have? “Don’t be limited by machine capabilities. Lasers gives you freedom for new designs.”
Remote laser welding and cutting are not typically used to produce ovens. Electrolux decided to break with tradition.
New concepts in the design and construction of structural elements of the car body save weight, time, costs and installation space.
If the founding family of Hayden had a motto it would most likely be: “Get tough.” Dan Hayden, the fourth generation to lead the family firm, explains why laser technology is one of the best ways to achive this
Laser welding is advancing into railroad car manufacturing on a wide front – a 16-meter-wide front to be exact.
Whatever method you use, aluminum is very difficult to weld. So Thomas Schnekenburger decided the laser was his best option.
The next generation of scanner optics will release the focus spot from the working plane. Here’s how users will benefit from this three-dimensional dance.
A small part makes a huge difference: the gasket silencer from KACO has put an end to loud water pumps
The car of the future should still be fast, comfortable, safe and able to go the distance. The car of the future should have very low CO2 emissions. But how?
